Trouble connecting to private app

Unrelated to the error you’re seeing but, make sure to connect over plaintext http (not https, unless you have self signed certs setup for the .internal domain) and that the server on the other side is also capable of serving plaintext http.


Just to be sure, you’re attempting to connect to private-app from another app within the same Fly org, correct?


I believe you’ve already checked,

  • flyctl dig _apps.internal TXT -a <app-name> (ex)
  • flyctl ips private -a <app-name> (ex)

…to ascertain if both the client app and the server (private-app) in your org have indeed been assigned 6pn IPs (if not, exec flyctl ips allocate-v6 --private -a <app-name>; docs)?

If so, can you try

  • flyctl ssh console -a private-app -C nslookup -type AAAA private-app.internal
  • flyctl console -a private-app -C nslookup -type AAAA global.private-app.internal

…and see what it prints (ex, docs)?
